DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 755,386, dated March 22, 1904.

.Application iiled November 9, 1903. Serial No. 180,475. (No inodel.) A

To MZ whom t may concern:

Be it known that vI, EDWARD J. FASSINO, a citizen of the United Statearesiding at Middletown, Orange county, State of New York, have invented certain new and useful Improvements in Door-Checks, of which the following isa specification suihcient to enable others skilled in the art to which the invention appertainsto make. and use the same.

My invention is designed to afford, simple but effective means whereby a 'door may be conveniently held orl stopped under various conditions of use, the device embodying the threefold function of a bolt, a holder, and a check, whereby the door may be secured in position when shut, held in anydesired position when open, and checked by a buffer if swung against the -wall or other opposed surface.

The invention consists in the special combination and arrangement of parts hereinafter described and claimed specifically.

In the accompanying drawings, Figure 1 is a front elevation of my door-controlling device 'applied to the lower edge of a door and illustrating its use as a bolt. Fig. 2 is a side elevation of the device, the door and sill being shown in section. Fig. 3 is a View similar to Fig. 2, illustrating the use of the device as a means for holding the door open at any angle. Fig. 4: is a sectional view of the door, showing a side elevation of my device with the manipulating-lever `drawn out horizontally and the buffer in contact with a side wall or other opposed surface. Fig. 5 is a plan of the device in the position shown in Fig. 1 in horizontal section. Fig. 6 isla horizontal section of a portion of the door, showing a plan of my device with the manipulating-lever down or closed. Fig. 7 is a rear elevation of the device, the rear plate being'removed and one of the side walls being shown in partial section, thebolt being in this view thrust downward. Fig. 8 is a section upon plane of line 8 8, Fig. 7, with the rear plate in position. Fig. 9 is aview similar to Fig. 7 with the bolt drawn. Fig. l0 is a transverse section upon plane of line 10 10, Fig. 9, with the rear plate in position. Fig. 11 is an elevation of the bolt; Figs. 12 and 13, respectively, a side elevation and a plan of the under or inner side of the manipulating-lever. Fig; 14 isa view of the lower end of the device.

O is the front plate of the casing formed with thevertical ribs c c, which constitute the side walls of said casing and to which the back plate ck is secured by screwsy c2 or `equivalent means.`

B is a bolt the lower end of which is formed in any suitable or desired manner, with a bearing block or cushion b, of rubberror other soft or resilient material. A convenient way of providing this yielding bearing b is to form a recess ZJ for its reception inI the end of the bolt, the rubber protruding beyond the end of the bolt, as shown in Fig. 8, althoughldo not limit myself to this particular structure, since it is obvious that any mechanical expedient may be resorted to, even a metallic spring' being substituted with like result and without departing from the spirit and intent of my invention in this respect, which contemplates the use of a yielding resilient bearingb at the lower end of the bolt B.

One side wall c of the casing is formed with a recess c3, in which is situated a spring-de tent d, provided with a V-shaped shoulder or projection for engagement with a notch or recess 52, formed in the opposed side of the bolt B, as shown in Fig. 9, for the purpose of sustaining the bolt in its raised or retracted position.

The upper end of the bolt B the slot b3 for the reception of the lower portion of the link L, which is pivotally connected to the bolt B, the upper portion of said link L being pivotally connected with the manipulating-lever M, the said manipulating-lever M and link L constituting practically a toggle-joint, by means of which the position of the bolt B may be forcibly controlled in either direction, according to the manner in which the lever M is manipulated. The inner end of the manipulating-lever is of course pivotally connected to the casing C, and vits outer end is provided with a buffer E, of any soft elastic material,.preferably rubber. A convenient method of forming this buffer is to attach a stud e to the end of the manipulatinglever M, said stud c being formed with an annular groove e for the reception and retenis formed with IOO tion of a ring of rubber @2. In this case the end of the stud e may be formed into a knob esto facilitate the manipulation of the lever M.

It is to be understood that the casing is countersunk into the door D and secured thereto by screws o4 04, passing through the flanges c5 c5, formed by the extension of the front plate C beyond the vertical ribs c c, as will be understood by reference to Fig. 1 in connection with Figs. 5 and 6.

In Figs. 1, 2, and 3, F represents a oor, S a door-sill, and s a mortise formed therein and gif a Wall or other surface opposed to the oor.

The operation of my combined bolt, holder, and buffer is` as follows, it being presumed that the manipulating-lever M is raised into thev horizontal position, as shown in Figs. 4 and 5, thereby raising the lower end. of the bolt B within the casing: The door D being closed may be bolted by depressing the outer end of the manipulating-lever M by anymeans convenient. This throws the lower end of the bolt B into the mortise s in the sill of the door and locks the latter shut. When it is desired to open the door D, the bolt B is of course again raised through the medium of the ma-v nipulating-lever M and link L. If thrown open carelessly or with undue force, the swing of the door-carries the buffer e into contact with thewallWor other opposed surface, the buffer in such case deadening ,and neutralizing the force of the blow and preventing injury. If' it is desired to hold the door 4open temporarily or otherwise at any angle with relation tothe door-frame, the door is placed and the bolt B lowered by depressing the manipulating-lever, as above described, thereby bringing the elastic and resilient bearing 'into contact with the floor-surface, as shown in Fig. 3, and by compressing. said bearing creating suiiicient frictional contact to hold the door in position.

It will v thus be seen that my improved de# vice, while necessarily designated as a do orstop and classed therewith, is essentially different from the ordinary door-stop, so called,

erating said bolt, the actuating-lever of said toggle-joint being formed with an elastic buffer for the purpose set forth. l

4. In a door-check, the combination with the casing countersunk in the door, of a bolt provided at its outer endwith a resilient contact,

and a toggle-joint confined within thedoor for operating said bolt, the actuating-lever of said toggle-joint beingformed` with a knob tofacilitate manipulation, land being also provided with a buffer extending beyond said knob.

5. In a door-check, the combination of acasing formed witha recess lfor the reception of aspring-detent, said spring-detent having a V-shaped shoulder, a bolt provided with a longitudinal recess and provided at its lower end witha resilient contact and formed with a notch for engagement with said vspring-detent, and a ltoggle-joint having onemember pivoted in said-recess-for actuatingsaid bolt, as set forth.v

6. 4In a door-check, the combination with the casing, of a' bolt B yprovided with the resilient contact I), and Athetoggle-joint for actuating said bolt, said toggle-joint being confined. in the door. and consisting ofthe link L and manipulating-lever M pivotally mounted in said casing and disposed. to throw said lever into a horizontal position at right angles to the face of the door to serve as a buffer, as set forth.

7 In a door-check, the manipulating-lever M, the stud e on said lever formed with the annular groove@l and the buffer e2 for the purpose set forth. y.

8. A door-check comprising the plate C, ribs c c one of which is formediwith therecess c3, the back plate c', the spring-detent d, the bolt Bprovided--with the resilient contact and formed with the notch b2, the link L, the manipulating-lever M .formed withthe stud e, knob-e3 and the buffer e2, the whole arranged and operating substantially as shown and described.
